IMPRQVEMENT IN Femme-MILLS.

The Schedule referred to in these Letters Patent and making pzut of the same To alljwhom tt may concern:

Be it known that we, WILLIAM BATES and FRED- ERICE BATES, both of SowerbyBridge, near Halifax, in the county of York, England, lhave invented a new and useful Improvement i'n Pulling-Mills, ot' which the following is a full, clear, and vexact description,

' reference being had to the accompanying drawiugtbriw I' parts.

This invention relates'tc machines employed in filliing or milling woolen fabrics; and

Our improvement consists lin the applicationl of an additional pair of nipping-or squeezing rollers, arranged at or ucar the delivery-endet' the trough which conducts'the fabric from the ordinary rollers.

Also, the inventionv consists in constructing for providing a curved back or curved 'surface of the lining of the machine, behind or opposite to the deliveryside of the additional rollers.

These rollers are driven at a suitable speed to receive the fabrics from' the trough without producing draft or pull, but exerting a pressure on and. forcing them against. the curved back, by which means the creases previously produced are removed, and. a

further fulling effect is produced on the fabrics.

{eferring to the accompanying drawing- A, B, and C are the ordir'iary rollers of the mill, and Y D, a guide for the fabric to the rollers B and (l, or, instead of said guide, verticalA rollers maybe used.

E is'the'trough or fulling-box, with its weighted flap or lid F, vfor pressing and retarding the fabrics as they are forced intov the trough by the rollers. A

These several partis and the frame-work are constructedand arranged as in other mills or machines for the like purpose. y

G land H are the additional pair of nipping or squeezing rollers, which it is preferred to vmalietinted. These rollers are applied near the delivery-end of the trough, and are driven or receive motion by belt and pulleys from the ordinary rollers B and C, and at the same surface speed, or thcreabout. 'They are made considerably longer than the rollers B and C, and may extend wholly across the interior of the machine, and

Yserve to receive the fabrics from the trough at the same speed as they enter; consequently the-trough always kept full, and the fabrics are forced or pushed y forwardv by said rollers against a curved back or cu-A '-fcdv surface of the lining I, and between itv and aneth: weighted iiap, J, hinged to the frame as atb, by which the fabrics are again pressed and retarded in their passage in asimilar manner as when they are passing through the trough li. p c

By means of these improvements a further fniling effect, or an increased actionon the fabrics, is produced at each passage through the machine, thereby great-ly facilitating the process of fullingr or milling woolen i fabrics.

Also, vthe fulling effect-s produced thereon are much better than heretoforeas, by' the action of the ordinary rollers B and C, the fabrics are" very much creased in .their longitudinal direction, and which `creases are not bythe machine, as heretofore constructed, afterward suiiciently removed, and the fulli'ng-is effected more in the breadth than in the length of the fabric, whereas, by our improvement,` tinl creases Aformed by the irst or narrow rollers B G, and usual Hange on the lower one of them, are removed by the second and longer or Wider rollers G H, and by the aid of the curved surface I and Hap J of suitable 'width to correspond with the rollers G H, the extrav or further fnlling effects are produced more -in the lengthv than in the breadth of the fabrics, which are desirable attainmen'ts, but the difference in this respect may be varied, that is, action on the fabric be increased or diminished in direction of its length, relatively to its width, by means of taper-pulleys S S and Witnesses to signature of WILLIAM BATES:
